There Is an International Team of Researchers Working on Training Dogs to Detect Covid-19

Let’s get back to Floki. He is part of an international consortium led by the National Veterinary School in Alfort, France, that aims to train specialized working dogs to detect covid-19. The University of Adelaide’s Anne-Lise Chaber and Susan Hazel say that the dogs are trained using sweat samples from people infected with covid-19.
According to Chaber and Hazel, when introduced to a line of sweat samples from people infected with covid-19, most dogs can distinguish positive samples from negative samples with 100% accuracy. During training, the dog’s nose goes into a stainless steel cone, which holds the sweat sample in a receptacle behind it. There is no physical contact between the dog’s nose and the sample.
